We report a fascinating phenomenon that emerges when a surface is viewed through a tube held close to one eye, with the other eye open. The disk-shaped area seen through the tube looks strikingly brighter and, when viewed on a textured background, also of higher spatial contrast than the same surface area viewed without a tube. The effect is reminiscent of a spotlight illuminating the area under consideration. We call this the 'tube effect'. The tube effect is one of the strongest contrast illusions known to us. It requires a matching luminance that is twice as high as the reference luminance seen through the tube. Brightness ratings increase linearly with the log of the background luminance. The effect (i) produces a dark afterimage, (ii) reverses in polarity with low ambient illumination, (iii) assumes the complementary colour of the illuminant, and (iv) persists with fully dilated pupils. Potential explanations include simultaneous contrast (due to the penumbra and dark inner walls of the tube) and veiling of the surround (due to local adaptation and a lower gain factor). 相似文献

Research data should be made readily available. A robust data-sharing plan, led by the principal investigator of the research
project, requires considerable administrative and operational resources. Because external support for data sharing is minimal,
principal investigators should consider engaging existing institutional information experts, such as librarians and information
systems personnel, to participate in data-sharing efforts. 相似文献

This study compared marital satisfaction among three age groups and examined how negative interaction patterns and religiosity relate to marital satisfaction at each age using a sample of Protestants (N = 45,387) diverse in denominations, location, geography, and size. We performed a 1-way ANOVA to compare marital satisfaction among three age groups (younger than 40, 40–59, and 60 and older) and found a U-shape curve with marital satisfaction highest among the youngest group, lowest among middle-age couples, and high among older couples. ANCOVA analysis found negative interaction, age, religiosity, age*negative interaction, and age*religiosity to be predictors of marital satisfaction. 相似文献

The amygdala receives multi-modal sensory inputs and projects to virtually all levels of the central nervous system. Via these widespread projections, the amygdala facilitates consolidation of emotionally arousing memories. How the amygdala promotes synaptic plasticity elsewhere in the brain remains unknown, however. Recent work indicates that amygdala neurons show theta activity during emotional arousal, and various types of oscillations during sleep. These synchronized neuronal events could promote synaptic plasticity by facilitating interactions between neocortical storage sites and temporal lobe structures involved in declarative memory. 相似文献

Psychopathology, social support, and interpersonal orientation were studied in relation to suicide attempt status in acutely suicidal, psychiatrically hospitalized Black adolescents and a matched sample of White adolescents. In the total sample, multiple attempters were differentiated by lower perceived support. Within the Black youth subsample, social comparison and positive stimulation from others differentiated multiple attempters from single attempters/ideators. Only suicidal ideation predicted multiple attempts among White youth and only higher interpersonal orientation predicted multiple suicide attempts within Black adolescents. 相似文献

巴哈伊教奠基者巴哈欧拉规定,应在每个巴哈伊社区的中心建立包括灵曦堂及附属机构的迈什里古勒-埃兹卡尔(意为对上帝的赞美发源之地),并面向所有宗教信仰者开放。这一机制把崇拜上帝和服务人类紧密地联系起来,体现了巴哈伊教的思想主张。本文通过对全球九大灵曦堂的详细介绍,以展现巴哈伊教的建筑艺术以及宗教同源、人类一体的精神。 相似文献

Power and the objectification of social targets 总被引:1,自引:0,他引:1

Objectification has been defined historically as a process of subjugation whereby people, like objects, are treated as means to an end. The authors hypothesized that objectification is a response to social power that involves approaching useful social targets regardless of the value of their other human qualities. Six studies found that under conditions of power, approach toward a social target was driven more by the target's usefulness, defined in terms of the perceiver's goals, than in low-power and baseline conditions. This instrumental response to power, which was linked to the presence of an active goal, was observed using multiple instantiations of power, different measures of approach, a variety of goals, and several types of instrumental and noninstrumental target attributes. Implications for research on the psychology of power, automatic goal pursuit, and self-objectification theory are discussed. 相似文献
